MetaVR has built 6,411 geocells of 3D terrain of the continent of Asia and the Middle East in its round-earth geocentric Metadesic format for rendering in Virtual Reality Scene Generator (VRSG). The 44,579,000 sq km virtual terrain was built with MetaVR’s Terrain Tools for Esri® ArcGIS® from 15 meters-per-pixel (mpp) color NaturalVue imagery, with 2.5 mpp SPOT satellite imagery of Afghanistan, 1 mpp black-and-white imagery of Iraq, Kuwait, and portions of Jordan, Lebanon, and Saudi Arabia color-fused with the 15 mpp base imagery, and 50 cm imagery of Hajin, Syria.
MetaVR's Asia 3D terrain includes 0.60 mpp high-resolution natural color insets of many capital cities and other areas of interest in many of these countries (listed in specification below). Terrain elevation information was based on 3-arcsecond DTED level 1 and void-filled SRTM (Shuttle Radar Topography Mission) elevation data, subsampled to achieve a nominal 60 m post spacing.
Several terrain regions include modeled areas of interest:
- Hajin, Syria
- Mischief Reef, South China Sea
- Afghan village in Kabul province, based on the village of Khairabad
- Dubai, UAE
- Bagdad, Iraq
- Seoul, South Korea
These MetaVR Metadesic (round-earth) terrain tiles are suitable for real-time visualization in MetaVR’s Virtual Reality Scene Generator™ (VRSG™) in applications such as simulation, and synthetic vision such as glass-cockpit displays, intelligence, surveillance, and reconnaissance (ISR) applications, close-air-support (CAS) exercises, and fixed-wing cockpit simulation.
The Asia 3D terrain is "Additional Materials" and is provided "as is" as described in our license agreement. Although MetaVR might modify or enhance the original source imagery, some visual artifacts from the source imagery might remain in the terrain tiles.
Geographic coverage by imagery resolution
The following symbolic representation shows the geographic coverage of this 3D dataset’s terrain tiles. This tile coverage map was generated with MetaVR’s Model Viewer. The green areas indicate use of 15 mpp imagery; the red areas indicate higher-resolution imagery.

MetaVR’s Asia 3D terrain is delivered on an external hard drive. The terrain is provided in MetaVR's round-earth Metadesic terrain format and will only run with a valid VRSG software license with valid software maintenance. A fee covers processing large quantities of data into Metadesic format and hard drive distribution media.
MetaVR’s Asia 3D terrain is available for purchase to MetaVR customers who are US Government agencies or contractors (for official use only). Customers can duplicate the data at their discretion as long as the data is used in conjunction with a valid VRSG license.
